Trait DmaDirection 

pub trait DmaDirection:
    'static
    + Debug
    + Sealed {
    const CAN_READ_FROM_DEVICE: bool;
    const CAN_WRITE_TO_DEVICE: bool;
}

DmaDirection limits the data flow direction of DmaStream and prevents users from reading and writing to DmaStream unexpectedly.

Required Associated Constants

const CAN_READ_FROM_DEVICE: bool

Whether the CPU can read data from the device.

const CAN_WRITE_TO_DEVICE: bool

Whether the CPU can write data to the device.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
